There are only three different army lists; Marines, Solar Auxilia, and Mechanicum.
The different legions all take from the same big army list, then have special abilities, new and unique units in different slots, and modifiers or restriction on units and wargear.
Further, each force can generally take a Rite of War (?) if you have a Praetor (your captain, basically) that modifies your troops and force org.
I'm sure a quick google search will reveal the specific rules for each legion and overview of their unique units.
